Description

Technical Field

[0001] This invention relates to the field of building technology, specifically to a foldable roof structure and modular building. Background Technology

[0002] As the most integrated type of prefabricated steel structure building, modular steel structure buildings are constructed by prefabricating components in a factory and transporting them to the site for assembly. Due to their advantages such as fast construction speed, low environmental pollution, and low requirements for weather and other construction conditions, modular steel structure buildings have been widely researched and applied in various countries.

[0003] In modular construction, after assembling the entire building using complete rectangular modules, a roof is still needed on top of the modular building due to requirements for waterproofing, architectural appearance, and thermal insulation. Typically, a pitched roof is used for aesthetic purposes. To ensure waterproofing, pitched roofs are usually constructed using a production and construction method that involves on-site fabrication and assembly of individual components, followed by the application of a waterproofing layer.

[0004] However, roof structures fabricated from parts on-site require assembly at the construction site, which significantly increases on-site workload and extends the construction period, thus diminishing the efficiency advantage of modular steel structures. To improve production efficiency, pitched roof structures are prefabricated in factories and then transported to the construction site. However, existing pitched roof structures suffer from low transportation efficiency and are difficult to secure during transport due to their slope. Summary of the Invention
